About On/Off Valves

On/Off Valves with Yor-Lok Fittings
For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Valves are standard port, so they slightly restrict flow.
Brass valves have good corrosion resistance.
Nickel-plated brass valves are more corrosion resistant than plain brass valves, and have a polished finish.
316 stainless steel valves are more corrosion resistant than brass valves.
Lockable lever handles can be fixed in place using a padlock (not included) with a shackle diameter up to 11/32".
Valves with T-handles are compact, allowing valves to be installed directly next to each other or in other tight spaces. They resist accidental movement when snagged or bumped.
Valves with oval handles resist accidental movement when snagged or bumped.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves have a PTFE seal and a corrosion-resistant 316 stainless steel body that can stand up to aggressive and corrosive solutions in chemical-processing applications. All are standard port, so they slightly restrict flow.

Diverting Valves with Yor-Lok Fittings
- Valve Type: Ball
- For Use With: Air, Argon, Helium, Krypton, Neon, Oil, Water, Xenon
- Seal Material: See table
For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Valves divert flow between ports. Turn the handle to direct flow from the bottom-port inlet to either side-port outlet. Valves are standard port, so they slightly restrict flow. All have threads and a hex nut below the handle for panel mounting.
Valves with flow shut-off can stop flow completely in addition to diverting flow between outlet ports.
316 stainless steel valves are more corrosion resistant than brass valves.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
